My T harrasses me about this pretty frequently. When the depression really kicks in, my energy goes, my motivation goes, and it is really easy to get stuck in that helpless/hopeless state, stuck in self-pity. For me, I don't really think there is any pay-off particularly. I am just frozen in the depression; it's like being stuck in quicksand. That's when T will tell me to get off my butt and DO something. Anything. Walk, go to Barnes & Noble to read instead of sitting at home on the couch, go out with my husband or my kids. Get out and move. It is SO hard to get myself to do anything. He's right though.
